Chennai Rain and Flood Disaster - time to think about unplanned urbanisation

Dear frined heavy rain in Chennai and the flood resulted is causing not only an emotional damage to society but also has a heavy toll on economy. 

Time to introspect- for me the reasons are clear - the existing infrstucture is not sufficient for the hugely gowing city. This is a classic exmaple of unplanned urbanisation infrastucture failure.

What do you think?
